I was wondering if you thought ETs were involved in either of the space shuttle explosions.

Also, I recall that after Challenger's accident there was a halt to all launches for several weeks. Then there was anew rocket launch scheduled (nit a shuttle) and the networks were covering it as the first launch after the accident, but that rocket veered off course or something like that. Than there was another waiting period followed by a newly scheduled launch of a rocket carrying a satellite and that launch also failed. Was it just NASA incompetence that created the series of failures or were the ETs sending a message?
